HINGE.

Application filed April 19, 1922.

To all w/zom t may concern:

Be it known that I; CHARLES R. Bnnx, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hinges; and I do hereby declare thev following to be a full, clear, and exact description of the invention, such as will ena-ble others lskilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in locomotive boilers, and more particularly to means for mounting the smoke box front of the same whereby they can be quickly and readily detached from the boiler and swung to an open position by means of an improved hinge member whereby access to the interior of the smoke box can be readily gained.

Another object of the invention is the provision of a new and improved hinged member for supporting a locomotive smoke box front whereby the same can be quickly and readily removed and replaced when it is desired to make repairs to the interior of the boiler or smoke box with a minimum amount of expense in the employment of labor or the usual block and tackle device used for removing these smoke box fronts.

As a general rule when it is desired to remove a smoke box front, it is necessary to erect a block and tackle device and several laborers are used for the assistance in removing this smoke box front, but by hinging the front onto the body of the locomotive boi-ler, the same can be quickly and readily detached from the end of the boiler or smoke box and swung to an open position by a single unskilled laborer and after the repairs have been made, the front can be quickly and readily returned to its closed position and secured by the usual bolt fastening means in a short space of time.

With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which:

Figure l is a side elevation of a boiler front end hinge constructed in accordance with my invention;

Fig. 2 is a top plan view"7 parts being broken away and illustrated in section;

Serial No. 555,648.

Fig. 3 is a similar view, the hinge being shown in an open position;

Fig. al. is a front elevation of the hinge member;

Fig. 5 is a plan view of one of the adjustable arms, and

Fig. 6 is a side elevation of the same.

Referring now more particularly to the drawings, the numeral l indicates a locomotive boiler having arranged at its outer end the usual securing ring 2 supporting a plurality of bolts 3 which are used in retaining the smoke box front 4 in its closed position against the end of the body member l. lt will be noted that the front 4 is provided with a plurality of perforations 5 adapted to receive the bolts 3 and after the bolts are placed in position within the perforations 5,r suitable nuts' 6 are threaded upon the outer ends of the bolts 3 to securely retain the front 4L in its proper position whereby to close the forward end of the body l of the smoke box end of the boiler.

As a general rule, this smoke box front end 4 is removed under difficulties requiring the services of several skilled laborers and the use of block and tackle in view of the weight of this boiler front, therefore providing considerable expense for the removal of this boiler front in order to obtain access to the interior of the boiler or smoke box when repairs are required. In

'order to eliminate the necessity of the requirement of several skilled laborers to remove this front end head besides the use of the block and tackle, l provide a new and improved hinge whereby the boiler front 4 is hingedly connected to one side `of the smoke box of boiler l and after removing the nuts 6 from the bolts 3 which retain the boiler front in its closed position, the same can be swung to an open position as shown in Fig. l by a single unskilled laborer, thus reducing the cost of the removal of these boiler fronts to a minimum. It will also be apparent that this operation can be carried out without the necessity of placing the locomotive in a Ioundhouse, but the front end can be readily u removed in the yards, on the main line or any other place where it may be required t0 gain access to the interior of the smoke box or boiler for repairs.

The hinge itself comprises a body plate 7 arranged to conform toy the general outlines of the body f the boiler 1 and secured upon the side of the body at the outer end thereof as shown in Fig. 1. Arranged at each end of the body plate 7 are th'e spaced ribs 8, the inner ends of which eX- tend beyond the inner longitudinal edge ot the body plate 7 and are integrally 'formed at their inner ends with the extension 9 formed at the ends of the pl-ate 7. These ribs 8 project outwardly at right angles to the plates 7 and are perforated to receive a pivot bolt 10. The plates 7 are urther provided at their ends with outstanding perforated ears 11 arranged midway between the ribs 8 and through which the pivot pins project.

Mounted upon the pivot pins 10 are the movable supporting arms 12, said arms be.- ing biturcated at their outer ends as shown at 13y to form spaced arms 14 arranged upon opposite sides of the lugs 11 and per-y forated as at 15 and 16, the perforations 15 being` adapted to receive the pivot pins 10, while the perforations 16 receive the pivot pins 17 that connect the ,arms to the front end- 4.

The inner ends of the arms 12 are slotted as at 18, said slot being adapted to receive an adjusting sleeve 19 which is threaded.

upon a bolt 20 supported bythe extension members 9 of the plate 7. The plate member 7- is attached to the body 1 of the boiler by means of suitable securing bolts 21 whereby this plate 7 can be quickly and readily detached from the body 1l or attached thereto as the occasion may require. The bolt 20 is provided at its inner end with a square head member 22 fitted within a square recess 23 formed in the inner face of the plate 7, the end of the head 22 abutting against the outer wall of the body member 1 whereby to prevent any movement on the part ofthe head 22. vThe outer end of the bolt 2O is provided with suitable screw threads 24 and mounted upon these screw threads is the adjusting sleeve 19 which is fitted within the recess 18 of each ot t-he arms 12. The sleeve 19 is provided adjacent its inner end'with a flange portion 25 adapted tov engage the inner face of the karms 12 adjacent the slot 18 while the outer end of the sleeve is provided `with, a nut 26 for `engagement with the outer face of each of the arms 12 said head portion 26 being preferably hollow to receive a lubricant to lubricate the screw threads 24. The sleeve 19 can be quickly and readily adjusted upon the boltA 20for adjusting the positions of the arms 12, relative to plate 7.

The boiler front end 4 is provided upon its outer tace and adjacent its circumferential edge with plates 27 having bracket arms 28 formed integral therewith, said plates being bolted or otherwise secured to the side extending recesses 31 adapted to receive lugs 32 which are carried by certain of the spaced ears 29 whereby the boiler front 4 will be re-` tained in its proper position prior to bolting` the same to the body 1.

Each of the pivot pins 17 are provided adjacent the head portion with a pinion 33, which is adapted to engage with the rack 34 formedupon one of the, longitudinal side walls of each of the, slots 30. From this it will be apparent that after the nuts 6 have been removed from the bolts 3 the, pivot pins 17 can be rotated by engaging any suitable tool with the heads 35,`the rotation of the pins imparting a similar movement to the lpinions 33 which'in turn will cooperate with the rack 34 and move the end portion 4 away from the front of the boiler. This movement will tend to remove the lugs 32 from the recesses 31 so as to permit the end member 4 to swing outwardly away from the end of the smoke boX.

From the above, it will be noted that by using a construction ot' this character, the end member 4can be moved away from the iront ot the smoke box with very little efort.

In Fig. 2, l have illustrated the d oor or head portion 4 of the locomotive in its closed position and in order to move the same from` the bodyl 1, the nuts 6 are detached from the bolts- 3 and the head 4 moves away from the body 1 until the lugs 32 are removed from the recesses31 to permit swinging Inovement of the front 4 through the medium of the bracket arms 28 and the supporting arms 12 which are pivotallyvconnected by means of the bolts 17 the open position ot the hinged members being illustrated in Fig. 3. From this it will be, apparent that a. single unskilled laborer can quickly and readilyv remove the locomotive boiler head 4 by removing the nuts 6 from` the ends of Vthe bolts 3 and prying outwardly upon the boiler head 4 until the same is moved a suiiicient distancey away from the body 1 to permit the removal ot the lugs- 32 rom the recesses 31.,V the door. or head 4 can then be swung upon the pivot pins 17, to an open position as illustrated in Figs.. 1 and l3.
